OSCLLATNG FAN. Y l

Specication of Letters Patent.

To all whom 'it may concern:

Be it known that I, EvnAn C. LIPPS, of Warren, in the county of Trumbull and State of Ohio, have invented certain new and useful improvements in Oscillating Fans; :ind I do hereby declare the following to be a full, clear, and exact description of the invention, such as' will'enable others skilled in the art to which it appertains to make and use the same.

The primary object of this invention is to .provide improved means for oscillating an electric fan motor regardless of Whether the latter be supported on a desk or secured toa wall or partition aswell as in the various positions in which the motor may be placed.

present invention the motor maybe oscil' lted regardless ot the positionitwmay occupy relatively to the support.

-Ti1e invention will be hereinafter fully set forth and particularly pointed onty in the claims.

In the accompanying drawings, Figui-e1 is a front eleuation. Fig. i? isa side View. Fig. 3 is a bottom plan View, with tlieinotor Fig. Li is s similar view showingl the parts in different positions. Fig. 5 is a section on line 5--5,

riff. e.

rteferring to the drawings, 1 designates n support or bracket which may rest directly u on a desk or table or be secured to a wa or partition. This sup ort has a yoke 2 between the arms of whic'i is pivot-- ally mounted a base plate 3 having a central opening to accommodate the neck d of the motor il, seid base plate being; secured to the yoke by screws 7 after the manne-r contenipiated by my before noted patent.'

the present instance i have shown the base plate as having; a depending extension 'la with which a locking screw 8 1s designed to en age for holding the base and motor in di ierent positions relatively to the sup Lettersi iatent of the United Statesv .No 9l9,898, dated April 2,7, 1909, i showed and described an electric tan' motor rote-- port. When ythe support'is secured to n. wall the motor and its basev are turnedat right angles i to the positions which they normally occupy relatively to the supportI i when the latter rests on a desk or table, but

the motor may be with equal facility/tilted and held at any desired angle intermediate the two extremes of movement. The plane of oscillation of the motor on tlie base is at right-angles to the planeof adjustment of the latter. j

For the purposeof oscillatin the motor,4 regardless of its position relatively to the support, l contemplate utilizing the motion of the armature shaft of the motor. The means shown comprises e lever itt-whichV is secured by e screw l2 to a. boss o the motor i casing and one'arm is-carried downwardly and bent rearwardly beneath the base, and at its rear end is` provided with an open-end slot 13' which takes in a lugI or screw 14 depending from such base. The forward end Patented June 31d, i910..

of the shorty arm of lever'l() is connected by a` link 15 to the outer end of a. crank 16 of a. straft 17 mounted at right angles to the armature shaft b .which it is driven thrt4 righ intermediate rc ucing gearing. For this purpose l have shown the armature shaft provided with e worm `18 in mesh with a pini-on 19 on a shaft 20 which carries a second but smaller pinion 2t which in turn meshes with a larger 'pinion 22 on shaft 17.

This gearing is inclosed 'in casings forming part of or attached to the motor easing. The crank shaft is located in the saine vertical plane as theY armature shaft of the motor; the lever 10 is fulcrumed in the same plane,

and the siiding engagementot its slotted endl with the sto uterine by lug 14 is likewise in the same p une. rlhns the entire device 'is made compact and free from projecting parts which are unsightly and require edditional room in the use of afan. tion of the armature shaft. is thus communicated et. e reduced speed tothe crank shaft,

.and theturning et' the tatter. through the The rotatain view points,

which said `le 'er 'has the motor is itself v'capable of beingturned Onan axis at right angles to the axis of the pivoted base.

Although I have shown the reducing gearing at the front of the motor, it is obvious that it ma if desired, be located at the rear thereof. n fact, it is immaterial, from cerhow the `power is transmitted from the armature shaft to effect the oscillation of the motor, since various means may be employed for this purpose. .I claim as my invention 1. In combination, a support, a base pivotally mounted on said support, means for holding said base in different positions relatively to said support, a motor rotatably mounted on said base so as to be capable of movement in a plane at right angles to the plane ofadjustment of such base, means for oscillating said motor relatively to said base comprising a crank shaft, a lever fulcrumcd on the motor and extended benelith said base, a stud extended from the base Wii and means for actuating said cran shaftl4 L 2. In combination, a lsupport, a ba'se pivotally mounted on said supportfineaisffor holding said base in different positions relatively to said'support, a motor rotatably mounted on said base so as to be capable'of movement in a. plane at right angles to the plane of adjustment of such base, means for oscillating'said motor relatively to said base comprising a crank shaft located in the same vertical p ane as the armature shaft of the motor, a lever fulcrumed on the motor in the same vertical plane as the crank shaft and the armature shaft,.said lever being extended beneath said base and having a sliding connection therewith at a point in the same vertical plane as the armature. shaft, and means actuated by said armature shaft for rotating said crank shaft,.which latter is connected to one arm of said lever.

3. AIn combination, a support, a base pivotall;7 mounted on said support, means for holding said base in different positions relatively to said support, a motor rotatably mounted on said base so as to be capable of movement in a plane at right angles to the plane of adjustment of such base, means for oscillating said motor relatively to said base a sliding en agement,

comprising a crank shaft at right angles to and on the same vertical plane with the armature shaft, reducing mechanism intermediate the tWo shafts actuated by the armature shaft, a lever fulcrumed on the motor in the same vertical plane as the crank shaft and extended beneath said base, a stop extending from the base in the same vertical plane as the fulcrum of the lever with which the latter has a sliding engagement, and a link connecting said lever to said crank shaft.

4. In combination, a support, a base pivotally mounted on said support, means for holding said base in different positions relatively to said. support, a motor rotatably mounted on said base so as to be capable of movement in a plane at right angles to the plane of adjustment of such base, means for oscillating said motor relatively to said base comprising a crankshaft at right angles to the armature shaft, reducing mechanism intermediate the two shafts actuated by said armature shaft, a lever fulcrumed on said motor at one side Aofthe base and i'n the same vertical plane as the armature shaft and having its long arm pivoted and extended downwardly and beneath said base and formed with a slot, a projection extending from said base through said slot, and a link connecting tliefother arm of said lever to said crank s ia t. i

5. The combination with a supporting base, of a motor mounted thereon, and means for oscillatin the motoren said base, such means comprising a lever fulcrumed on the motor at one side of the base and on the same vertical plane as the armature shaft of the motor, the long arm of said lever being extended beneath said base and having a slot therein, a stop extending from the base in the same vertical plane as said armature shaft and with which the slotted portion of the lever has a sliding engagement, and means operated by the armature shaft for actuating the said lever.

In testimony whereof, I have signed this specification in the presence of two subscribing Witnesses.
